UNITED lSTATES PATENT OFFICE.

HENRY SANDERS, OF UTIOA, NEW YORK.

IM PROVEM ENT lN CULTlVATOR-TEETH.

Specification forming part of Letters Patent No. 26,297, dated November 29, 1859.

To all whom it may concern Be it known that I, HENRY SANDERS, of Utica, Oneida county, State of New York, have invented a new and useful Improvement inthe Manner of Constructing Cultivator-Teeth of Sheet Metal and Cast-Iron Combined, ot'which the following is a full and clear description.

,I am aware that cultivator-teeth have been made of sheet metal in different ways. One kind is fastened to the cultivator-frame by a Wooden wedge, the tooth being mortised in the frame, and the wedge driven in perpendicular with the tooth between the tooth and the frame. This mode ot' making teeth requires heavy timber for the frame, and much labor is required to mortise them in. Another mode is tocast a head or boss on the tooth for the purpose ot' attaching the tooth to the frame; but in consequence of casting the head on the tooth the head chills and becomes hard and brittle and breaks loose from the tooth, thereby renderiu g it useless. j j y My improvement is intended to remedy these defects.

It consists of two pieces of metalexclusive of the bo1t,the tooth being formed of sheet steel or iron, with Bauges on the upper end ot' it, which goes next to the frame. The other i piece is made of cast-iron, with anges on't corresponding with the fianges on Vthe tooth for the purpose of securing the tooth firmly to the cultivator-frarne by means of a bolt passing through it and the frame. In order, also,

one pin, as it were, which is let into the frame by a hole being bored for that purpose, to receive it, so that when the tooth is fastened to the frame by the bolt this rim on the chair and projection on the tooth act as a brace against the pressure on the tooth when in use, adding strength and durability to it.

To enable any ordinary mechanic to `make and construct myinvention,Iwil1 now proceed to describe it in detail, reference being had to the accompanying drawings, making part of this specification, in which- ,'Figure 1 is a perspective view of the tooth.

Fig. 2 is a perspective view of the chair; and

Fig. 3 is a view ofthe tooth complete, ready to be attached to the cultivator-frame.

Fig. 1 is a tooth swaged out of sheetV metal or iron, a piece being cut out of it on each side to allow theiianges to be turned and the semicircular projection to beleft standing. a 01 are the flanges, and B the semicircular` projection. l Fig. 2 is the chair, made of cast-iron, with The angcs a a and semicircular projection B on the tooth,and the flanges 0,0 and pin E l on the chair, when constructed and arranged in relation to each other in the manner substantially as described, and for the purposes set forth.
